TO WHOM IT MAY CONGERN:

Known all men that'we, WILLIAM COOPER, Jr., and WILLIAM D. RUMSEY, of Howell, in the conntyof Livingston, and State of Michigan, have invented certain new and useful Improvements in Snap-Hooks;. and

declare the following to be a true and accurate description thereof, reference' being had to the accompanying drawings, and to the letters of reference marked thereon, a.nd making part of this specification, in which- Figure 1 is a perspective view, :ind

Figure 2 is a longitudinal sectional view.

A is the body of @snap-hook, of nearly the ordinary slm-pe, which is constructed with a recess, B, and provided at its point with a. socket, C, to receive the end of the bolt D. A

A longitudinal hole, E, is formed in the'shank of the hook, in line with the socket at its point, of suiicient diameter to allow the bolt D to operate freely therein.

I A shoulder, F, is formed on the bolt D, and an internally-flanged thilnble, G, containing a. spiral spring, H, embracing the smaller diameter of the bolt D, is driven into the longitudinal hole E, whic`h is 'chamfered suiiiciently to receiveit to the proper distance.`

I is a. proper head to the bolt D. Having thus described our invention, and named its various parts, we will now proceed to describe tho method of operating the same. A

The opera-tor seizing the snap, with his thumb on the Ibolt-head I, withdraws the bolt D, and inserting the ring or link into the hook,`releases `the bolt, which is forced forward into the socket C, on the point of the hook,

by the action of`the spring H, thus retaining it in the hook until released by the withdrawalof the bolt, which 1 must be voluntary.

What we claim as cui: invent-ion, and desire to secure by Letters Patent, is The snap-hook A, when, prp'vided with the opening B andV pin D, h'nving a. shoulder, F, a. spring, E, a thimble, G, anda. head, I, all constructed and arranged to operate substantially a's described.
